it does need a different design, but a buried oscillator, 5 to 8 meter
deep in the garden has the best temperature stabilization, just don't
turn thee power off, but that could be done using the old Greek
water-clock principle, the spill over stabilizer. In the Bay Area
[California] the soil's
Deep soil temperature stability is a bit of a myth, mainly because not many
people actually measure it.
I measured a beautiful 0.2C degree annual sine wave 15 metres down in limestone
in Kentucky.
The catch is the Gauss's Error function drop-off rate of temperature
fluctuation is a very
good
Greetings,
Started following the discussions recently and am learning a lot. Found
the temperature sensor thread interesting. Measuring contact
temperature (enclosure, heat sink) is a different problem than air
temperature. For closing temperature control loops the absolute
accuracy is
An oscillator can take many weeks to settle in after being powered off /
shipped / abused / looked at cross-eyed / etc. It typically takes a
Thunderbolt a month or two to settle down after being shipped from China.
Agree with Marks comments.

Hi
A lot depends on the oscillator. My fine old GR rack mount took most of 9
months to settle most of the way. It was still dropping in a year after that
when I stopped watching it. Some of my T-Bolts took a week, some took a couple
months….
Best thing you can do with any OCXO is just leave

They actually had a PR blurb about this on the local TV news

Jim,
You must be hanging out in the streets again. You need to stop that.
